` A CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS` CURTAIN CONSTRUCTIONApplication filed August 18, 1932. Serial No. 629,257.`

This invention has to do with window curtains of the type used inautomobiles, and is particularly concerned with the construction of thehatten in the hem at the lower edge of the curtain and the way in whichthe pull cord for the curtain is secured to the hatten.

The purpose of the invention is to provide an improved batten ofinexpensive construction which is so shaped at the location of the pullcord as to` facilitate attachment of the latter, produce a connection ofneat and pleas ing appearance, prevent the hatten from turn ing in thehem, and maintain the batten centei-ed with respect to the ends of thehem.

Other more specific objects and advantages will be apparent to thoseskilled in the art upon a. full understanding of the special shaping andpurpose of the cord-supporting portion of the batten.

In order that the invention may be readily understood, two slightlydifferent structural forms of the same are presented herein, but it willof course be appreciated that such forms are intended primarily for thepurpose of exemplitication and that* the invention is susceptible ofembodiment in other structurally modified forms coming equally withinthe scope of the appended claims.

In the accompanying drawing:

Fig. 1 is an insideV face view of an automobile window curtain equippedwith the improved batteri;

Fig. 2 is a fragmentary view correspond- Jing to the central portion ofFig. 1, showing in more detail the special shaping of the bat- 1 ten atthe location of the pull cord;

Fig. 3 is a vertical transverse section through the assembly, taken online 3 3 of Fig. 2; and

Figs. 4 and 5 are views, corresponding to Figs 2 and 3, respectively, ofa modified form of the invention.

The form of the invention shown in Figs. 1, 2 and 3 will first bedescribed. In those views a soft fabric curtain 10 is shown mounted on aspring-wound roller 11 and poi sitioned at the inside of a window 12.The

curtain has a hem 13 at its lower edge in is preferably a straight metalrod of circular cross section, and the ends of the same, which projectequal distances beyond the ends of the hem, are preferably flattened outin a horizontal plane and' apertured to provide small eyelets 15,similar to those shown in Hamm Patent No. 1,841,730 of Jan. 19, 1932,for the reception of vertically extending guide cords 16.

At the center of the hatten 14 the latter is tiattened out andapertured, in a vertical plane ati right angles to the plane of theeyelets 15, whereby to provide a recess or seat 17 for the reception ofa pull cord 18. The side walls of the hem 13 are provided, at pointsopposite the seat 17, with holes 19 which permit passage of the cord 18through the hem into engagement with the seat. Y

The cord 18, which is usually in the form of a loop.` with a tassel 20attached to the same, is threaded through the holes 19 across the seat17 and then looped back about itself beneath the hem is a tight-ly drawnslip knot.

The cord- 18 thus pulls directly against the` seat portion 17 of therod, in a small tie formation which is disposed entirely beneath theupper edge of the hem, and the cord portion which pass through the holes19 across the seat 17 engage with the sides 21 of the seat upon anytendency of the rod to shift endwise in the hem, thereby maintaining theguide cordeyelets 15 evenly spaced from the ends of the-hem and inhorizontal positions at all times, the underslung disposition of theseat 17 with respect to the top of the rod Serving to leep the rod fromturning out of its proper position. i

In the modification shown in Figs. 4 and 5, the seat 22 on the hatten 23for the reception of the pull cord 24 is produced by downwardlyoffsetting the rod at the location of the cord. By constructing the seatin this way, the latter is broughtbelow the top surface of the rodproper and the converging sides 25 of the seat bind with the cord uponany tendency of the rod to move endwise.` In this embodiment of theinvention, as well asl in the first described form, the formation of theseat produces a slight downward bulge in the roddirectly beneath theseat, which yso bulge may cause the rod to fit the hem quite snugly atthat point and thereby further assist in prevent-ing any movement of therod in the hem.

The improved batten and pull cord assembly which forms the subjectmatter of this invention provides a very neat and secure connectionbetween the parts, while at the same time permitting of easy insertionor removal of the rod, it being merely necessary to unloop the cord 18to free the rod.

I claim:

l. In a window curtain assembly of the type described, a curtainprovided with a hem at its lower edge, a batten positioned in the hemand provided at its center with a seat below the level of the top of thehatten, and a pull cord passing through openings in the side walls ofthe hem opposite the seat into engagement with the latter.

2. In a window curtain assembly of the type described, a soft fabriccurtain provided with a hem at its lower edge, a substantially straightround wire bat-ten positioned in the hem and provided at its center witha curved seat below the level of the top of the hatten, and a pull cordpassing through openings in the side walls of the hem opposite the seatinto engagement with the bottom of' the latter.

3. In a window curtain assembly of the type described, a soft fabriccurtain provided with a hem at its lower edge, a substantially straightround wire hatten positioned in the hem with its ends projectingtherefrom and provided at its ends with horizontally disposed eyeletsfor sliding engagement with vertical guide cords and at its center witha recess below the level of the top ot the hatten, and a pull cordpassing through openings in the side walls of the hein opposite therecess into engagement with the bottom of the latter, said cord being sopositioned with respect to the sides of the recess in the hatten as toprevent any appreciable endwise movement of the hatten in the hem.

4. In a window curtain assembly of the type described, a soft fabriccurtain provided with a hem at its lower edge, a substantially straightround wire batten positioned in the hem with its ends projectingtherefrom, said batten having its projecting ends. flattened out in ahorizontal plane and apertured for the reception of guide cords andhaving its center portion flattened out in a vertical plane andapertured, and a pull cord passing through openings in the side walls ofthe hem into the aperture in the center portion of the hatten.

5. In a window curtain assembly of the type described, a soft fabriccurtain provid` ed with a hem at its lower edge, a substantiallystraight round wire batten positioned in the hem with its endsprojecting therefrom, said batten having its projecting ends {iat-WILLIAM S. HAMM.
